While an effect like that of "Banisher of the Radiance" or "Macro Cosmos" is active, it is impossible to discard a card to the Graveyard. The activation costs of the effects of "Jowgen the Spiritualist", "Abyss Soldier" and "Return of the Doomed" require you to discard a card to the Graveyard, which is impossible, so you cannot activate their effects. However, the activation costs of effects like "Magic Jammer" only require you to discard a card, so you can activate their effects since the card does not need to be discarded to the Graveyard.[3]

While the effect of "Dimensional Fissure" or "Macro Cosmos" is active, you cannot activate effects which have "discard to the Graveyard" or "send to the Graveyard" as costs. Thus, you cannot activate the effect of "Honest" which increases ATK, since you cannot send it to the Graveyard as a cost.[4]

Versus Specific Cards

"At the end of the Damage Step", as mentioned in the text of cards like "Legendary Jujitsu Master", occurs at the same time as "when the monster which is destroyed by battle is sent to the Graveyard". Or, if "Macro Cosmos" or "Banisher of the Radiance" is active, then this occurs at the same time as "when the monster which is destroyed by battle is removed from play".[5]

Previously Official Rulings
